From wells and elevators to cranes and windmills, pulleys move the world and the Engino Discovering STEM Mechanics: Pulley Drives set shows how.

Young mechanics start with the fundamentals (fixed vs movable pulleys), then level up to compound systems to feel the force-distance trade-off of mechanical advantage. They’ll experiment with driver/follower pulley diameters to change speed and output torque, calculate velocity ratio, and see how standard vs crossed belts reverse rotation or reroute motion.

Every build ties directly to the booklet’s theory pages, experiments, and quizzes, making abstract physics concrete and memorable. Extra 3D instructions are available via kidCAD (3D Viewer).

Customer Reviews (4.8 / 5 · 5 reviews)

David M. ★★★★★

The step-by-step guide made it easy for my 11-year-old to build the glider model, and the rubber-band launcher really shows how thrust works. We've already rebuilt it twice to test different wing angles.

Penelope Y. ★★★★★

My 10-year-old spent a solid two hours building the crane and wouldn't stop until the pulley actually lifted a small load. The step-by-step instructions for each of the 10 models are clear enough that he barely needed my help. Good pick for a kid who likes figuring out how things move.

Benjamin ★★★★★

The windmill model actually spins when you crank the handle, which my son thought was the coolest thing. Took him about an hour to assemble with the instructions, and he's already asking to try the elevator next.
